3,136,056 DISPOSABLE SAFETY RAZOR WITH INTEGRAL BLADE Roland Reynier,9204 Viola, Bakersfield, Calif. Filed June 21, 1962, Ser. No. 204,096 2Claims. (Cl. 30-47) This invention relates to new and usefulimprovements in safety razors of the throw-away type and has for itsprimary object to provide, in a manner as hereinafter set forth, animplement of the character which may be manufactured at such low cost asto make its disposal after a single use, if desired, economicallyfeasible.

Another important object of the present invention is to provide animproved throw-away or disposable safety razor of the aforementionedcharacter wherein the complete device, including the blade, may beexpeditiously produced from a single sheet of suitable metal.

Still another object is to provide a disposable safety razor comprisingan integral tubular handle, open at both ends, which may accommodatesuch articles or products as a miniature tube of shaving cream, a shortstyptic penoil, etc.

Other objects of the invention are to provide an improved, one-piecedisposable safety razor which is of relatively simple construction,strong and durable, compact and of light weight.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawing forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of a one-piece disposable safety razorconstructed in accordance with the present invention;

FIGURE 2 is a view in vertical longitudinal section through the device;

FIGURE 3 is a plan view of the blank;

FIGURE 4 is a cross-sectional view through the handle, takensubstantially on the line 44 of FIGURE 2; and

FIGURE 5 is a view in vertical longitudinal section through the forwardportion of a modified embodiment of the invention.

Referring now to the drawing in detail, it will be seen that theembodiment of the present invention which has been illustrated inFIGURES l to 4, inclusive, of said drawing comprises a longitudinallysplit tubular handle of suitable metal which is designated generally byreference numeral 6. Of course, the handle 6 may be of any desiredlength and diameter. As shown to advantage in FIGURE 2 of the drawing,the handle 6 is of uniform diameter throughout and open at both ends.

Formed integrally with one end of the tubular handle 6 is a head 7. Thehead 7 includes a substantially rectangular plate 8 having formedintegrally with the upper portion thereof a generally segmental flange9. The flange 9 extends at an acute angle from the plate 8 and theperipheral edge 10 thereof is joined to one end of the tubular handle 6by an integral connection or neck 11. It will be noted that the flange 9is joined at 11 to the handle 6 at a point diametrically opposite thelongitudinal seam or split 12 of said handle.

The plate 8 of the head 7 has formed therein a generally U-shaped slotor opening 13 comprising tapered end or leg portions 14 and providing anintegral blade 15 having a bevelled cutting edge 16. The longitudinalmarginal portion of the substantially rectangular plate 8 which isremote from the flange 9 is turned or bent rearwardly to provide a guard17 for the cutting edge 16 of the blade 15, said guard paralleling saidcutting edge in spaced relation thereto.

2 Ice It is thought that the use of the razor will be readily apparentfrom a consideration of the foregoing. As shown in FIGURE 3 of thedrawing, the complete razor is produced from a blank 18 comprising asingle sheet of metal. The blank 18 includes a substantially rectangularplate 19 which is rolled to provide the handle 6. Of course, the handle6 is gripped in either hand and the blade 15 is drawn over the skin inthe usual manner. The member 17 functions as a gauge and a guard for thecutting edge 16 of the blade 15, as will be understood. The constructionand arrangement are such that the blade 15 and the guard 17 are bendablyadjustable relatively to each other. The tubular handle 6, beingunobstructed and open at both ends, is adapted to receive thereinminiature shaving cream tubes, short styptic pencils and other articles.As illustrated to advantage in FIGURE 2 of the drawing, the guard 17 isof arcuate cross-section to glide smoothly over the skin withoutirritating. In the embodiment shown in FIGURE 1 of the drawing, theblade 15 and the legs or arms 20 of the generally U-shaped guard 17 arecoplanar. In FIGURE 3 of the drawing reference numeral 21 designates theline on which the plate 8 is bent to provide the flange 9.

Of course, the blade 15 may be of any suitable dimensions. As shown toadvantage in FIGURE 2 of the drawing, the construction and arrangementis such that the blade 15 will prevent such articles as miniatureshaving cream tubes, styptic pencils, etc., from sliding out of thehandle 6 through the forward end thereof.

In the modification of FIGURE 5 of the drawing, reference numeral 22designates a handle of a suitable plastic or other material on which thehead 7 is mounted. Toward this end, one end portion of the plastichandle 22 has formed therein a kerf 23 in which the flange 9 of the head7 is fixedly secured in any suitable manner. In other respects this formof the invention is substantially similar to the embodiment of FIGURE 1of the drawing.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

1. A one-piece disposable safety razor comprising an elongated tubularhandle, a generally planar rectangular head plate longitudinally spacedfrom one end of the tubular handle, an angularly related flange integralwith one edge of the plate, said flange having side edges convergingfrom a maximum width at approximately said one edge of the plate, and arelatively narrow neck integral with the narrow end of the flange andsaid one end of the tubular handle, said head plate having an elongatedslot adjacent the free edge thereof, said slot terminating at each endin a rearwardly extending slot forming inv eflect a U-shaped slotdefining a blade portion, the edge of the blade portion bordering thefirst mentioned elongated slot being bevelled so as to form a cuttingedge,

the portion of the plate between the first mentioned elongated slot andthe free edge of the plate being downwardly bent so as to form a guardfor the cuttingedge parallel to said cutting edge.

2. A disposable combination razor head and blade consisting of a singleflat sheet of metal angularly bent so as to form a single thicknessplate and a flange depending at an angle therefrom, said plate having anelongated slot adjacent the free edge thereof, said slot terminating ateach end in a rearwardly extending slot forming in References Cited inthe file of this patent UNITED STATES PATENTS Foltis Apr. 24, 1951 SamkoJuly 27, 1954 Eberbaugh Feb. 3, 1959 Kuhnl Nov. 10, 1959
